Nationals 7, White Sox 4
Dan Haren rebounded from his disastrous Washington debut to pitch five solid innings and Bryce Harper and Ryan Zimmerman each drove in two runs as the Nationals finished a three-game sweep of visiting Chicago.
Denard Span and Jayson Werth each had two hits and scored twice for Washington, which improved to 6-0 at home. Alejandro De Aza and Jeff Keppinger each had two hits and drove in a run for the White Sox.
Things fell apart in the fourth for White Sox starter Dylan Axelrod (0-1), who allowed six runs and seven hits in 3 2/3 innings.
After allowing a one-out double to Haren and a two-out single to Werth to put runners at the corners, Axelrod uncorked a wild pitch to score Haren and give Washington a 4-3 lead. Axelrod then intentionally walked Harper, and Zimmerman followed with a two-run double to right to break it open.
Haren (1-1) struck out five and allowed three runs on 10 hits to atone for a debut in which he allowed four home runs against the Reds. Rafael Soriano worked around a two-out single in the ninth for his fifth save.
